Abstract

There is a need for more palynological studies of the bogs and lakes in those area of the world which were covered by the last glaciation (approx. 12,000 years ago for N. America). Such data must be correlated with data from bogs and lakes of the same age in Europe, Asia and Eurasia to complete the post glacial climatic picture for the northern hemisphere. To facilitate such studies, a key to the pollen types commonly found in bog peats, supported by illustrations would seem to be desirable. The key presented here features a simpler terminology for the morphology of the grains, followed by more technial descriptions in the text. Such a key may be of use to students at many levels.
